Unfortunately, I've taken my Super Cub down and I no longer remember specifically what LIPO I used. I think it was this one

but I am not sure. I know that I had to cut the battery box to make it fit.
The 3 cells gave the motor a great boost. Some said it might wear the motor out over time. If so, A replacement motor is only five or ten dollars.

Again, there are TONS of guys/gals who have done this exact thing the Super Cub threads are here and on RCG, also. READ those threads before doing anything and you will be well served. Rich
